He should.
One match isnt good enough to judge someone. Give him the whole series first.
Frozen feet at debut match ? It could happen.
Lack of footwork ? If he lacks in some technical abilities, I'm sure the coaches will work with it.
Wish we had a batting coach like Jamie Siddons who transformed I-charge-down-the-wicket Tamim into who he is today. Our batting unit looked whole lot better at the end of Siddon's tenure than what he had to begin with. Anamul's 41 was shaky to begin with but looked good as it progressed.

Will be a big test for him tomorrow, specially after WI team had a look at him and would also want to focus on that footwork issue.
